Specication of Letters Patent.

Y Patented J an. 19, 1915.

Application filed January 13, 1914. Serial No. 811,801.

Be it known that I, FREDERICKP. Ros BACK, a citizen of the United States, residing at Benton Harbor, in the county of Berrienand State of Michigan, have invented a new and useful Improvement in Perforating-Machines, of which the following is a specification. i

My invention relates to an improvement inmachines forxperforating sheets to form therein weakened tearing lines; and my prmary object is Yto provide such a machine to perforateat one'operation the lines to eX- tend at right angles to each other as they are used, say, in bank-check books, wherein the checks on each sheet have Vperforated tearing-lines between them extending at Yrightangles to a perforated line between the checks and the stubs. In the description hereinafter contained these lines are termed, respectively, v the check-line and the stub-line.

In the accompanying drawings, Figure l is aview in side elevation of my improved machine with a part of the gear-wheel casing broken away; Fig. 2 is a broken view showing in sectional elevation the clutch for operating the perforating mechanism; Fig. 3-is a'n enlarged section of the same on line 3, Fig. 1;V Fig. 4 is' a view of the machine in rear elevation; Fig. 5 is a section on line 5, Fig.4:-, showing an eccentric; Fig. 6 is a plan section of the machine on the irregular line 6'-6, Fig. 7;-Fig. 7 is a section of the machine on line 7, Fig. 9; Fig. 8 is a broken plan View showing a gage-device; Fig. 9 is a section on the irregular line 9 9, Fig. 7; Fig. 10 is a broken view in section on line l0, Fig. 7, showing the stub-line perforating head; Fig. 11 is an enlarged section on line 1l, Fig. 10; Fig. 12 is a plan view of a sheet perforated by my improved machine; Fig.V 13 is an enlarged vertical section of a check-line perforating-head K as shown in Fig. 9; Fig. 14 is a similar view with the perforating head in its lowered position of operating on a bunch of sheets, and Fig'. 15 is a section on line 15, Fig. 13. Y

The frame of the machine is formed of two side-members 16, 16 having extensions 17, 17 bolted to them on their upper ends and containing corresponding vertical rectangular slots like the one shown at 18 in Fig. 1. -A head 19 is reciprocably confined in these slots at its ends, with which are conand its cop- Y tween its ends with a spring-raised treadle 27 and carries on one end a pawl 28. This pawl cooperates with a clutch-device 29 on the shaft 21. The shaft contains a semi-cylindrical recess 30,' and the hub 22a of the gear contains a similar recess 3l and two rectangular recesses 32 opposite each other. A pin 33 has a semi-cylindrical intermediate section, working in the hub-recess 30 and normally held by a spring 3e in a position to protrude one corner beyond the confines of that recess into the path of the recesses 32, whereby when the protruding part of the pin strikes a recess 32 in the rotation of the shaft, the latter carries about with it the gear 22 to reciprocate the head 19. The pawl 28 extends normally into the path of a finger 3e projecting from the pin, so that at the end of each rotation of the gear the iinger strikes the pawl to turn the pin 33 and house its semi-cylindrical section in the recess 30 and thus release it from engagement with a recess 32, thereby disconnecting the gear fromV the shaft. Each time the gear is to lbe rotated, the operator depresses the treadle 27 to withdraw the pawl out of the path of the finger 31 and free the spring 34 to turn the pin andprotrude it for engagement with a recess 32 to rotate the gear. A. feed-table 35 is shown adjustably supported in proper position and is provided near its forward edge with a groove 36 of inverted T-shape for guiding a gage 37 in setting it on the table. 'Ihe gage, which is of rectangular cross section, has pivotally connected with its upright section the head of a T-shaped guide 37a carrying setscrews 38 for truing the gage and having a guide-tongue 39 confined in the groove and releasably clamped to the stem of the yguide 37a by a thumb-screw 40.

The parts thus far described need involve no Yfeatures of novelty.

vThe shape in cross-section ofthe reciproeating head 19 is best shown in Fig. `7. It contains in the face of its forwardly-projecting ledge-portion 19a a groove 19b for confining a horizontal bar 41 bolted to the top of a punch-head 42 to' carry the latter. rThis punch-head carries, for perforating thestub-line, headed punches 43 supported in aline of holes in a narrow ledge 44 formed in the back of the lower edgej'of-v the head and held against risingby astop-bar 45 fastened to the inner face ofthe punch-head to extend over the heads of the punches. The head 42 works, for guiding it in its reciprocating movement,l between an outer bar 46, shown to be provided on its. front face with upper and lower horizontal reinforcing flanges, and an inner bar 47 .f rlhese guide-bars are securely bolted to' the forward edges of the upper side-members 17 of the frame. The ends of the bar 46k are extended backwardly across the ends of: the head 42 (Fig. 6) for conlining the latter end-wise; and this bar carries near the bottom of its inner face a stripper 46a, through which the punches worlrand are guided into holes in a femaledie plate 48 (Fig. 11) supported in horizontal line with the upper surface of thefeedtable below the space 49 for the sheets while undergoing perforation.` The head 42 is provided, with vertical slots 42a into which extend pins 42 from the bar 46 for guiding the movement of the head.

Vlith the punches 43 coperate headed punches 50 extending at right-angles thereto to perfor-ate the check-lines. Five sets or rows of thesecheck-line punches are shown to bei provided inV the present machine, though the number may be Vgreater or smaller. The ,punches 50 in each row are supported in holes in a ledge 52 on the face near the lower edge of a punch-head 51 and confined against risinglby astop-bar 53 eX- tending over their heads. rl`hese punches work through guide-holes in avledge 52a on the lowerLpart of the face of the bar 56. Each head 51 has a thickened upper portion formed to fit at its upper edge the contour of the bottom of the reciprocating'head 19, containing arecess 54 (Fig. 7) formed by a projection 55, whereby the punch-carrying head is stably connected with the head 19 but' may be adjusted, by sliding, lengthwise 0f the latter. Back of each head 51` isV supported` a guide-plate 56, with which it is adjustably connected by washer-equipped bolts 57, passing through vertical slots '58 in the f punch-carrying head; and feathers 51a on the, backs of these heads workin grooves 51-b in the faces of the plates 56 for guiding the heads in moving. Each guide-plate has in one lateral edge an upperre'cess 59 toreceive a'rib60 on the rear face of the inner guide-bar 47, and a lower recessv 61 to receive a ribi.62 projecting on a horizontal bar 63 bolted'kon the frame; and the opposite edge of each guide-plate 51 has formed in it a rectan-guiar recess -64vto embrace a bar 65 having a scale of inches and fractions of an Yinch marked off along its upper face, this bar being bolted at its ends to the rear edges of the frain'e-inenibers 17 .i Vertical bars 66,- bolted throughtheir endsto the rear edges of the guide-plates 56,' hold the latter on the scalebar 64, which is .recessed at 67 in its` outer face, against. which work set-screws 68 in the vertical bars for clamping. the guide-plates rigidly inthe positions to whichl theymay bey adjusted, on loosening. the set-screws,- by sliding `them along the. bar 65 andthe ribs 60 and thereby carrying withtheni, the heads 51. ri'he punches 50 work through holes lin female-die strips 69 on. ledges 69, onthe lower partsof the faces of theguideplates 56, which are shown to be slotted longitudinally to aEord the space 49 into. which to insertinto position the sheets to be perforated, and of which a plurality may be operateduponat once;l O'nthe lower ypart of the outer Vface of the, guide-bar 46; is shown to be, fasteneda sheet-metal guard- 46b for Aguiding into thev space 49 the forward edges of sheets vwhenoutv of line, as-by curling upwardly.

is will thus be seen, heads, or any of them, may be adjusted along the bar and guided in their adjustnient by the scale on the latter', by loosening the set-screws 68V and moving the heads k56 along their bearings 60, 62 Aand 65, which render their movement true, and thereby also sliding the punch-heads 51 along the recess and projection 55 onv the reciprocat; ing head 19, which securely hold the punchcarrying heads lin adjusted position. y

Sheets to be perforated with stub-,lines 71 and check-lines 72 A(FigiQ) are Hlaid, on the Vtable with their left-hand edges against the gage, and with the parts of the machine in the positions' in` which they are illustrated, wherein the check-punching heads are properly adjusted-tol-producethe check-lines 7 2, the sheetsare. introduced into` position to be perforated under the lineslof punches, when their advance-edges will strike stops 7 3. One of these stops isshewn in Fig. 8 as a bar 74 marked off onone side with a scale of inches andufractions of an inch, and terminating at` its forward end in an upright finger formingA the, stop' 7 3. The bar 74 is supported to permit it tolbe moved longitudinally, for adjustment, in a jaw 75, to which the bar is,V fastened-duits adjusted position by a thumb-screw 7 6; and

the jaw embraces a ledge 77 onthe rear party ofthe frame, to which it is fastened by a set-screw 7 8. Vith these stops suitably adjusted to properly admit thes'heetA or sheets into position tobe perforated, aftergintre: ducing the sheet orV sheets, and with theme' the check-punching` A tor 25 running to drive the gear 22, the operator depresses the treadle 27 to cause the gear to be clutched to and rotate the shaft 25. Each rotation of the shaft reciprocates the head 19 and works the stub and check punches to perforate the sheets as the sheet 70 is shown to be perforated. Each line of the punches is shown to incline downwardly from one end to the other. This is to cause them to perforate with a stroke like that ofa shear-blade, which is a known expedient for saving power in operating the punches.

I realize that considerable variation is possible in the details of construction thus specifically shown and described, and I do not intend by illustrating a single, specific or preferred construction of my invention to be limited thereto; my intention being in the following claims to claim protection for all the novelty there may be in my in- Vvention as broadly as the state of the art will permit.

What l claim as new and desire to secure by Letters Patent is l. In a perforating machine, the combination with a frame, of a reciprocating head, a pair of spaced guide-bars extending across the front of the frame, a punchequipped head carried by the reciprocating head to work between said bars, a vertical guide-plate extending at a right-angle to said guide-bars and having a recess in its rear end, upper and lower ribs respectively on the inner guide-bar and frame entering recesses in the opposite endof the guideplate, a scale-bar secured to the rear side of the frame and embraced by the rear recess in the guide-plate, a bar secured to the rear end of the guide plate to extend across the scale-bar and carrying a set-screw tobear against the scale-bar, and a punch-equipped head carried by the reciprocating head to work, simultaneously with said rst-named punch-equipped head, across a face of the guide-plate.

2. In a perforating machine, the combination with a frame, of a reciprocating head, a punch-equipped head carried by the reciprocating head to work crosswise of the frame, a longitudinally-slotted vertical guide-plate adjustably supported to extend. at a right-angle to said punch-equipped head, sheet-stops, each comprising a jaw secured on the rear part of the frame and provided with a socket and a scale-bar adjustably confined in the socket and terminating at its forward end in one upright stop-finger, and a punch-equipped head carried by the reciprocating head to work, simultaneously with said first-named punch-equipped head, across a face of the guide-plate.

3.
